Essential Characteristics for LVL in Loadbearing Applications

LVL is governed by two different EU standards, including for loadbearing applications. This depends on its classification as either a material used for manufacturing structural components (in a similar way to glued laminated timber) or as a product for use in both non structural and structural situations.

APA’s advice here refers to buildings and bridges, and the structural, loadbearing requirements of EN 14374.  Refer also to its definition as a product, covered by the performance chacteristics under EN 14279.

Note: Not all characteristics are required in every member state. Where there are no regulatory requirements on that characteristic for the intended end use, manufacturers are not required to determine or declare the performance of their product with regard to a specific characteristic. They can use the option ‘No performance determined’ (NPD) in the information accompanying the CE marking. The NPD option may not be used where the characteristic is subject to a threshold level.
